Special clamp is designed to solve the existing problem in the high precision machining of multiple free-form surface. The formula to determine the key parameters of clamps is given through analysis of model. The method to install and test the clamp is shown to assure the accuracy of mutual alignment for multiple free-form surface. It provides theoretical evidence to reduce the system errors in the process and measurement. The structure can resolve the problem of clamp and positioning of the workpiece when machining a measurement, the repeatability and positioning accuracy is high, and the positioning references determination is easy. The foundation is established for the high-precision of machining the free-form surface.
